Answer 3

I would start by find the difference between the listed terms
1,3,9,19,33,51,73,
2, 6, 10, 14, 18, 22, ...

now find the difference of this second sequence:
4,4,4,4,4...

so we see the pattern.
now work backwards.

can you do that ?

Answer 4

in other words, extend the sequence
2, 6, 10, 14, 18, 22
by adding 4 to find the next term.
we get 26,30,34
add 26 to the last term in the original sequence, to get the next term

Answer 5

oh i understand now thank you

Answer 6

so the next 3 terms are:
73+26
73+26+30
73+26+30+34

Answer 7

so the next three numbers are 99 129 163 correct
